Audi B5 S4 2.7t Coilpack Wiring Harness
Made in house for your Audi B5 S4 2.7t, upgrade your OEM 3-pin coil packs and ICMs with 2.0t/R8 coil packs and completely eliminate the weathered original wiring at the same time.
This harness connects pins direct into your ECU, designed to layover the existing harness, meaning if you remove the engine, the harness is not trapped in the firewall/ECU box.
Installation instructions can be found on our 'Instruction Guides' page.
**Please expect a lead time of 1-2 weeks for this product.**
